Ngati tikufuna kumanga malo osungiramo zinthu zozizira, gawo lofunika kwambiri ndi gawo losungiramo zinthu zozizira, choncho ndikofunikira kwambiri kusankha malo oyenera osungiramo zinthu zozizira.
Kawirikawiri, malo osungiramo zinthu zozizira omwe ali pamsika amagawidwa m'mitundu iyi:
Malinga ndi mtundu wake, ukhoza kugawidwa m'magulu oziziritsidwa ndi madzi ndi magulu oziziritsidwa ndi mpweya.
Zipangizo zoziziritsira madzi zimakhala zochepa kwambiri chifukwa cha kutentha kwa malo ozungulira, ndipo zipangizo zoziziritsira madzi sizikulimbikitsidwa m'malo omwe ali pansi pa zero.
Malo otchuka kwambiri pamsika wonse ndi malo oziziritsira mpweya. Choncho tiyeni tiganizire kwambiri za malo oziziritsira mpweya.
Kuti tiphunzire chipangizo choziziritsira, choyamba tiyenera kumvetsetsa kapangidwe ka chipangizocho
1. Chokometsera cha mufiriji
Mitundu ya ma compressor osungira zinthu zozizira ndi iyi: Semi-hermetic cold storage compressor, screw cold storage compressor ndi scroll cold storage compressor.
3. chosungira madzi
Zingatsimikizire kuti madzi oziziritsa m'firiji akuyenda bwino mpaka kumapeto.
Chosungira madzi chili ndi chizindikiro cha mulingo wamadzimadzi, chomwe chimatha kuwona kusintha kwa mulingo wamadzimadzi komanso ngati pali firiji yochuluka kapena yochepa mu dongosolo malinga ndi katundu.
4. Valavu ya Solenoid
Chophimba cha valavu cha solenoid chimapatsidwa mphamvu kapena chopanda mphamvu kuti chizimitse chokha payipi
Chokometsera chozungulira
Ngati zofunikira pakusungirako zinthu zozizira ndi mphamvu yoziziritsira zili zochepa, compressor yozungulira ingagwiritsidwe ntchito.
2. Cholekanitsa mafuta
Imatha kulekanitsa mafuta oziziritsa ndi mpweya woziziritsa womwe uli mu utsi.
Kawirikawiri, compressor iliyonse imakhala ndi cholekanitsa mafuta. Mpweya wozizira komanso wotentha kwambiri umatuluka kuchokera mu cholowera mafuta, ndipo mafuta oziziritsa amasiyidwa pansi pa cholekanitsa mafuta. Mpweya wozizira ndi mafuta ochepa oziziritsa amatuluka kuchokera mu cholowera mafuta ndikulowa mu condenser.
5. Gawo la Condenser
Monga chida chofunikira chosinthira kutentha mu makina oziziritsira, kutentha kumasamutsidwa kuchokera ku nthunzi yotenthedwa kwambiri ya refrigerant yokhala ndi kutentha kwakukulu komanso kupanikizika kwakukulu kupita ku condenser kudzera mu condenser, ndipo kutentha kwa nthunzi ya refrigerant kumatsika pang'onopang'ono kufika pa saturation point ndikusungunuka kukhala madzi. Zinthu zodziwika bwino zoziziritsira ndi mpweya ndi madzi. Kutentha kwa condensation ndi kutentha komwe nthunzi ya refrigerant imasungunuka kukhala madzi.
1) Chokonzetsera mpweya chotuluka m'thupi
Chokondetsa chotulutsa mpweya chili ndi ubwino wokhala ndi kutentha kokwanira, kutulutsa kutentha kwakukulu komanso kugwiritsa ntchito mosiyanasiyana.
Ngati kutentha kwa malo kuli kochepa, siyani kugwira ntchito kwa fan, yatsani pampu yamadzi yokha ndipo gwiritsani ntchito firiji yoziziritsidwa ndi madzi yokha.
Kutentha kukatsika pansi pa nthawi yozizira kwambiri, samalani ndi madzi oletsa kuzizira.
Ngati katundu wa dongosolo ndi wochepa, poganizira kuti mphamvu ya condensation si yokwera kwambiri, ntchito ya pampu yamadzi yozungulira yoziziritsa ndi nthunzi imatha kuyimitsidwa ndipo kuziziritsa mpweya kokha ndi komwe kungagwiritsidwe ntchito. Nthawi yomweyo, madzi osungidwa mu thanki yamadzi ozizira ndi chitoliro cholumikizira madzi amatha kutulutsidwa kuti asaundane, koma panthawiyi, mbale yowongolera mpweya yolowera mpweya iyenera kutsekedwa kwathunthu. Njira zodzitetezera pakugwiritsa ntchito pampu yamadzi ndi zofanana ndi za condenser yamadzi.
Pogwiritsa ntchito evaporative condenser, ziyenera kudziwika kuti kukhalapo kwa mpweya wosasungunuka m'dongosolo kudzachepetsa kwambiri kusinthana kwa kutentha kwa evaporative condensation, zomwe zimapangitsa kuti condensation ikhale yokwera kwambiri. Chifukwa chake, ntchito yotulutsa mpweya iyenera kuchitika, makamaka m'dongosolo lotentha lotsika lomwe lili ndi mphamvu yotsitsa mpweya mufiriji.
pH ya madzi ozungulira iyenera kusungidwa pakati pa 6.5 ndi 8.
2) Kondensala yozizira ndi mpweya
Choziziritsira mpweya chili ndi ubwino wopangidwa mosavuta komanso chimapereka mphamvu zokha kuti chigwiritsidwe ntchito.
Chokometsera chosungiramo zinthu zozizira chopanda kutentha kwambiri
Ngati mphamvu yosungiramo zinthu zoziziritsa kuzizira ikufunika kukhala yayikulu koma kukula kwa polojekiti yosungiramo zinthu zoziziritsa kuzizira kuli kochepa, compressor yosungiramo zinthu zoziziritsa kuzizira ya Semi-hermetic imasankhidwa.
Chokonzetsera mpweya chikhoza kuyikidwa panja kapena padenga, zomwe zimachepetsa malo ogwira ntchito komanso zofunikira pa malo oyikamo ogwiritsa ntchito. Mukagwira ntchito kwa nthawi yayitali, pewani kuyika zinthu zosiyanasiyana mozungulira chokonzetsera mpweya kuti musakhudze kayendedwe ka mpweya. Nthawi zonse onani ngati pali kutayikira komwe kukukayikiridwa monga madontho a mafuta, kusintha kwa kutentha ndi kuwonongeka kwa zipsepse. Nthawi zonse gwiritsani ntchito mfuti yamadzi yamphamvu kwambiri potsuka. Onetsetsani kuti mwadula magetsi ndipo samalani za chitetezo mukatsuka.
Kawirikawiri, kupanikizika kumagwiritsidwa ntchito polamulira kuyambika ndi kuyimitsa kwa fani yoziziritsa mpweya. Chifukwa fani yoziziritsa mpweya imagwira ntchito panja kwa nthawi yayitali, fumbi, zinthu zosiyanasiyana, ubweya, ndi zina zotero zimakhala zosavuta kuyenda kudzera mu coil ndi zipsepse ndi mpweya ndipo zimamatira ku zipsepse pakapita nthawi, zomwe zimapangitsa kuti mpweya usamayende bwino komanso kuti kupanikizika kwa mpweya kuwonjezere. Chifukwa chake, ndikofunikira kuyang'ana nthawi zonse ndikusunga zipsepse za fani yoziziritsa mpweya kukhala yoyera.
screw mtundu ozizira yosungirako kompresa
Ngati mphamvu yosungiramo zinthu zozizira ili yaikulu ndipo ntchito yosungiramo zinthu zozizira ili yaikulu, compressor yosungiramo zinthu zozizira yamtundu wa screw nthawi zambiri imasankhidwa.
